Not everyone can just learn such coping mechanisms. Some people have physical problems that need physical help/remediation. Of course, our current psychiatric drugs are their risky attempts to help such folks. It is all very tricky, but we should all learn how to have better attitudes and behaviors.
I agree, and the profit motive for the pharma corps seems to have really compromised their ethics (to put it mildly while giving them more benefit of doubt than I think they deserve).
Ultimately, medical science didn't even know the brain had a lymphatic system until this century. Futzing with the subtle biochem of neurotransmitters and hormones is quite beyond their abilities, looks to me. That doesn't appear to prevent them from making a solid off their profit, regardless of any negative results.
And, always, RIP Chris Cornell. Man, we miss that man's voice.
